naling headed rollers in bearings thereof and the remaining. rollers journaled in the remaining bearings thereof. Balls having been placed between the rollers in the grooves thereof, the several casing sections may be respectively placed over the several assemblages of antifriction elements. lVith the bearing sections and antifriction elecaused to engage the respective steps 11" and 12.

The bearing being placedand adjusted, the screws & a're detached to permit the rings 5 to revolve .with the rollers 3 around the shaft X.

v It will be understood that this bearing can be readily assembled and. applied to any part of a line of shafting, being adjustable `to effect its accommodation tothe position of the shafting, and so that grindingand wearing are avoided.

Having described -my invention, I claim:

1. A bearing having separable parts with complementary cylindrical surfaces races, rollers containing races, balls engagand ing said races, sectional rings engaging the ends of said rollers, and means for securing the sections of said rings to the respective separable parts aforesaid.

2. A casing having separable parts provided with complementary races, cyhndrlcal surfaces, and grooves, rollers provlded .with races, balls engaging said races, sectional rings engaging the ends of said rollers, sectional rings engaged in lsaid grooves, and means for engaging sections of sald first. and second named rings together, whereby rollers and balls aforesaid are engaged to each of said separable parts,

3. A casing having separable parts provided With complementary races and cylindrical surfaces, rollers provided with spindles and races, balls engaging said races, ring sections having notches engaging said spindles, and means for engaging said ring sec-tions tothe respective separable parts ,i

aforesaid whereby balls and rollers aforesaid are engaged within respective separable parts aforesaid. v

4. Aitasing having separable parts provided with complementary cylindrical sur'v faces and channels, rollers engaging said surfaces, said rollers having spindles,` separable ring sections engaging said spindles, a ring section engaging a channel of one of said parts and extending into the channel of the other of said parts, and means for engaging said last named ring section to a ring section aforesaid.
